Dynamic reports::how to display report output in a frameset

bhanu_k

Hi,

I hope this is a right forum to ask my question.As per my requirement I need to generate dynamic reports using BIRT API,In Servlet when I run the report using IRunAndRenderTask.run() method report output is displayed without a frameset in browser. Please let me know the steps or API methods/parameters to display the report in BIRT default frameset.Below is a snapshot of my code thanks in advance.



public void doGet(HttpServletRequest reqest, HttpServletResponse response)
throws ServletException, IOException {

//get report name and launch the engine
response.setContentType("text/html");
String reportName = reqest.getParameter("ReportName");
String[] cols = (String[])reqest.getParameterMap().get("dyna1");
ServletContext sc = reqest.getSession().getServletContext();
this.birtReportEngine = BirtEngine.getBirtEngine(sc);

IReportRunnable design;
try
{
//Open report design
design = birtReportEngine.openReportDesign( sc.getRealPath("/Reports")+"/"+reportName );
ReportDesignHandle report = (ReportDesignHandle) design.getDesignHandle();
buildReport( cols, report );

//create task to run and render report
IRunAndRenderTask task = birtReportEngine.createRunAndRenderTask( design );
task.setAppContext(new HashMap());

//set output options
HTMLRenderOption options = new HTMLRenderOption();
options.setOutputFormat(HTMLRenderOption.OUTPUT_FORMAT_HTML);
options.setOutputStream(response.getOutputStream());
task.setRenderOption(options);

//run report
task.run();
task.close();
}catch (Exception e){
throw new ServletException( e );
}
}

Hi Bhanu,

Since you are using BIRT in a servlet environment, is it possible for you to use the Sample WebViewer App instead of using Birt through the API?

'Sample WebViewer' provides nice UI and I would suggest you atleast see it once if you have not seen it already. It is a separate web-app which can run independently in Tomcat (or other servers) and then pass report file name as URL parameter to open the report.
So from any page in your current web-application, you can simply have an html frame and within it send request to the WebViewer Sample App. Your reports will be shown beautifully within this frame.

[Ignore if you have reasons of not using the WebViewer ]
